q=m.c.t
i need to make the equation = m.
I think the answer is m=c.t +q
is this right...muliplying in rearanging confuses me.

q = mct
To isolate m, divide both sides by ct.
q/(ct) = (mct)/(ct)
Notice the ct cancels out.
q/(ct) = m

m.c.t = q
divide the left side of equation by t to get rid ot t. if u divide left side u must also divide right side by t,
m.c = q/t
divide left side of equation by c to get rid of c. also divide right side by c
m = q/t divide by c
you do know that c means c/1
when u divide q/t by a fraction you got to switch the numerator and denominator the other way around i.e 1/c then u multiply q/t by 1/c
so you get
m = q/tc or
m = q/ct
they are both the same

rearranging is actually very easy as long as you do it step by step so you don't get confused so for this one...
- we want to isolate m so from what is given m is "stuck" with c and t
- what we want to do is to get rid of c and t on the right side of the equation
step 1:
q = m*c*t
step 2: (to get rid of c on the right side, we divide both sides by c)
(q) / c = (m*c*t) / c
step 3: (simplify)
q / c = (m*t*c) / c
q / c = m * t * (c / c)
q / c = m * t * (1)
q / c = m * t
step 4: (to get rid of t on the right side, we divide both sides by t)
(q/c) / t = (m*t) / t
step 5: (simplify)
(q/c) / t = (m*t) / t
(q/c) * (1/t) = m * (t / t)
q / (c*t) = m * (1)
q / (c*t) = m
step 6: (by convention, m should be on the left side, so we can simply just flip the equation around so right side to left side and vice versa)
q / (c*t) = m
m = q / (c*t)
therefore, the equation rearranged to m= is....
m = q / (c.t)

what does your dot mean? If it meant multiply then
m = q/(ct)
divide ct on both sides to isolate m

you just have to transpose them.
q=mct
since it's times, you have to divide them to get to the other side.
q/ct = m or m=q/ct

The ct is multiplying the m so, to have m on its own, DIVIDE BOTH SIDES by ct:-
q / (ct) = m.(ct) / (ct)
q / (ct) = m
Note that (ct) / (ct) = 1

i think youre subject is THERMODYNAMICS..
THe specific heat Q=mass*cx*(T2-T1)
cx.... 1. cv--constant volume process (isometric)
2. cp--constant presuure(isobaric)
3.ct--constant temperature (isothermal)
m=Q/cx*delta T or by pvt equations.. m=pv/RT

It is m = q/ct

q=m.c.t
q/t=m.c
q/(t.c) = m
so m= q/(c.t)
